Unless you've been living vacuum-sealed under a rock on the ocean floor, the hook to Song of the Summer 2014 "Fancy" has surely wormed its way into your ear. And last summer, you couldn't walk into a party without "I Love It" blasting to the stratosphere. These two insidiously catchy songs have one thing in common, and that's Charli XCX.

With these two hits under her belt—Charli XCX sings the hook on "Fancy" and wrote "I Love It"—she's got a pretty good claim to burgeoning pop stardom. And now Charli XCX has dropped this late summer anthem dripping with 'tude. The August doldrums are perfect for dancing and shouting, "I don't wanna go to school. I just wanna break the rules." You know how it feels. [Amazon, Spotify, iTunes]
